Hereinafter, embodiments of the present disclosure will be described indetail with reference to the accompanying drawings.

FIG. 1 is a view schematically showing the construction of a displaydevice 100 according to an embodiment of the present disclosure, FIG. 2is a plan view schematically showing a display panel of FIG. 1 , andFIG. 3 is an enlarged view showing pixels provided in area A of FIG. 2 .

Referring to FIGS. 1 to 3 , the display device 100 according to theembodiment of the present disclosure includes a display panel 110, anoptical module 120, a panel driving unit 130, an optical driving unit140, a controller 150, and a memory 160.

The display panel 110 includes a plurality of pixels, and displays acolor image. The display panel 110 may be realized using an organiclight-emitting display panel, a liquid crystal display panel, a plasmadisplay panel, a quantum dot light-emitting display panel, or anelectrophoretic display panel.

The display panel 110 may include a display area DA, in which pixels areformed to display an image, and a non-display area NDA, which displaysno image.

The non-display area NDA may be disposed so as to surround the displayarea DA. The panel driving unit 130, which supplies various kinds ofsignals to a plurality of signal lines in the display area DA, and alink unit (not shown), configured to connect the panel driving unit 130and the plurality of signal lines to each other, may be formed in thenon-display area NDA.

In the display area DA, a plurality of pixels is disposed to display animage. As shown in FIG. 2 , the display area DA includes a first displayarea DA1 and a second display area DA2.

The first display area DA1 is an area that does not overlap an area CA,in which the optical module 120 is disposed, and displays an imageirrespective of operation of the optical module 120. The first displayarea DA1 may be formed so as to have a large size.

A plurality of first pixels P1, each of which includes at least twofirst subpixels SP1, may be provided in the first display area DA1. Eachof the plurality of first pixels P1 may include a light-emitting pixel.Specifically, each of the at least two first subpixels SP1, included ineach of the first pixels P1, may be a light-emitting subpixel includinga light-emitting device to emit a predetermined color of light. Each ofthe first pixels P1 may include at least two of a red subpixelconfigured to emit red light, a green subpixel configured to emit greenlight, and a blue subpixel configured to emit blue light. As an example,one of the first pixels P1 may include a red subpixel and a greensubpixel, and an adjacent one of the first pixels P1 may include a bluesubpixel and a green subpixel. As another example, each of the firstpixels P1 may include a red subpixel, a green subpixel, and a bluesubpixel.

The second display area DA2 overlaps the area CA, in which the opticalmodule 120 is disposed. An image to be displayed in the second displayarea DA2 may be decided depending on whether or not the optical module120 is operated. Specifically, in the case in which the optical module120 is not operated, the second display area DA2 may display an imagetogether with the first display area DA1. In the case in which theoptical module 120 is operated, on the other hand, the second displayarea DA2 may display no image or may display a black image. At thistime, an image may be displayed in the first display area DA1.

The size, position, and shape of the second display area DA2 may bedecided in consideration of the optical module 120. The second displayarea DA2 may be provided at the position corresponding to the opticalmodule 120. In addition, the second display area DA2 may be provided soas to have a size including therein the area CA, in which the opticalmodule 120 is disposed.

A plurality of second pixels P2, each of which includes at least twosecond subpixels SP2, may be provided in the second display area DA2. Inthe second display area DA2, the plurality of second pixels P2 mayinclude light-emitting pixels and non-light-emitting pixels, unlike thefirst display area DA1. Each of the light-emitting pixels may be an areaincluding a light-emitting device to emit light, and each of thenon-light-emitting pixels may be an area including no light-emittingdevice and transmitting external light. That is, areas including nolight-emitting devices and transmitting external light may be providedin the second display area DA2, unlike the first display area DA1.

Each of the at least two second subpixels SP2, included in each of thelight-emitting pixels, among the second pixels P2, may be alight-emitting subpixel including a light-emitting device to emit apredetermined color of light. Each of the light-emitting pixels, amongthe second pixels P2, may include at least two of a red subpixelconfigured to emit red light, a green subpixel configured to emit greenlight, and a blue subpixel configured to emit blue light. As an example,one of the light-emitting pixels, among the second pixels P2, mayinclude a red subpixel and a green subpixel, and an adjacent one of thelight-emitting pixels, among the second pixels P2, may include a bluesubpixel and a green subpixel. As another example, each of thelight-emitting pixels, among the second pixels P2, may include a redsubpixel, a green subpixel, and a blue subpixel.

Each of the at least two second subpixels SP2, included in each of thenon-light-emitting pixels, among the second pixels P2, may be anon-light-emitting subpixel including no light-emitting device andtransmitting external light.

As a result, the number of light-emitting subpixels provided in a unitpixel area UPA of the second display area DA2 may be less than thenumber of light-emitting subpixels provided in the unit pixel area UPAof the first display area DA1. For example, as shown in FIG. 3 , fourlight-emitting subpixels may be provided in the unit pixel area UPA ofthe second display area DA2, whereas 16 light-emitting subpixels may beprovided in the unit pixel area UPA of the first display area DA1.

Light transmittance of the second display area DA2 may be changeddepending on the number of light-emitting subpixels provided in the unitpixel area UPA thereof. In the case in which the number oflight-emitting subpixels provided in the unit pixel area UPA isincreased, luminance and resolution of the second display area DA2 mayincrease, whereas light transmittance of the second display area DA2 maydecrease. In the case in which the number of light-emitting subpixelsprovided in the unit pixel area UPA is decreased, on the other hand,luminance and resolution of the second display area DA2 may decrease,whereas light transmittance of the second display area DA2 may increase.In a display panel 110 according to an embodiment of the presentdisclosure, the number of light-emitting subpixels may be decided inconsideration of luminance, resolution, and light transmittance of thesecond display area DA2.

The first display area DA1 and the second display area DA2, describedabove, may be different in transmittance and resolution from each other.The first display area DA1 may have first transmittance, and the seconddisplay area DA2 may have second transmittance, which is higher than thefirst transmittance. In addition, the first display area DA1 may havefirst resolution, and the second display area DA2 may have secondresolution, which is lower than the first resolution.

The optical module 120 may be disposed at the rear surface of thedisplay panel 110. The optical module 120 may be provided so as tooverlap the display area DA, specifically the second display area DA2,of the display panel 110. The optical module 120 may include allcomponents configured to use external light input through the displaypanel 110. For example, the optical module 120 may be a camera. However,the present disclosure is not limited thereto. The optical module 120may be an ambient light sensor or a fingerprint sensor.

The panel driving unit 130 controls driving of the display panel 110based on a control signal received from the controller 150. To this end,the panel driving unit 130 includes a gate driving unit and a datadriving unit.

The gate driving unit generates gate signals for driving gate lines ofthe display panel 110 in response to a gate control signal received fromthe controller 150. The gate driving unit supplies the generated gatesignals to the subpixels SP1 and SP2 of the pixels P1 and P2 included inthe display panel 110 via the gate lines.

The data driving unit receives a data control signal and an image datasignal from the controller 150. The data driving unit converts adigital-type image data signal into an analog-type image data signal inresponse to the data control signal received from the controller 150.The data driving unit supplies the converted image data signal to thesubpixels SP1 and SP2 of the pixels P1 and P2 included in the displaypanel 110 via data lines.

The optical driving unit 140 controls driving of the optical module 120based on a control signal received from the controller 150.

The memory 160 stores shape information of the second display area DA2.The shape information of the second display area DA2 includes positioninformation of a starting point, vertical length information of thesecond display area, and line-based direction information and widthinformation indicating the border of the second display area.

The controller 150 changes an image that is displayed in at least one ofthe first display area DA1 and the second display area DA2 of thedisplay panel 110 using the shape information of the second display areaDA2 stored in the memory 160. Specifically, the controller 150 maygenerate display area information and border information of each of theplurality of pixels using the shape information of the second displayarea DA2. The controller 150 may changes an image that is displayed onthe display panel 110 using at least one of the display area informationand the border information of each of the plurality of pixels, and mayperform control such that the changed image is displayed on the displaypanel 110.

Hereinafter, the memory 160 and the controller 150 will be described inmore detail with reference to FIGS. 4 to 12 .

FIG. 5A is a view illustrating a starting point and verticallength of the second display area and direction information when thesecond display area has a U shape, FIG. 5B is a view illustrating astarting point and vertical length of the second display area anddirection information when the second display area has a circular shape,and FIG. 6 is a view illustrating left border information and rightborder information. FIG. 7 is a view showing an example of a seconddisplay area having a U shape, and FIG. 8 is a view showing an exampleof the shape information of the second display area shown in FIG. 7 .FIG. 9 is a view illustrating an edge area and a border pixel, and FIG.10 is a view showing an example of display area information of each of aplurality of subpixels. FIG. 11 is a view showing the construction of animage processing unit of FIG. 4 , and FIG. 12 is a view showing anexample of a blurring filter.

Referring to FIGS. 4 to 12 , the memory 160 stores the shape informationof the second display area DA2, and the controller 150 corrects an imagethat is displayed in at least one of the first display area DA1 and thesecond display area DA2 of the display panel 110 using the shapeinformation of the second display area DA2 stored in the memory 160.

The shape information of the second display area DA2 may includeposition information of a starting point, vertical length information ofthe second display area DA2, left border information about a left borderlocated at the left side based on a central axis C of the second displayarea DA2, and right border information about a right border located atthe right side based on the central axis C of the second display areaDA2.

The position information of the starting point may include X-axis andY-axis coordinate values at a certain point of the border of the seconddisplay area DA2. One or more starting points may be included dependingon the shape of the second display area DA2.

As an example, as shown in FIG. 5A, the second display area DA2 may havea U shape. In the case in which the second display area DA2 has a Ushape, a plurality of starting points may be provided. The startingpoints may include a first starting point S1 located at the left side ofthe central axis C and a second starting point S2 located at the rightside of the central axis C.

Position information of the first starting point S1 may include anX-axis value notch_s1 x of the first starting point S1 and a Y-axisvalue notch_sy of the first starting point S1. Position information ofthe second starting point S2 may include an X-axis value notch_s2 x ofthe second starting point S2 and a Y-axis value notch_sy of the secondstarting point S2. The Y-axis values of the first starting point S1 andthe second starting point S2 may be identical to each other, and theX-axis values of the first starting point S1 and the second startingpoint S2 may be different from each other. However, the presentdisclosure is not limited thereto. Both the Y-axis values and the X-axisvalues of the first starting point S1 and the second starting point S2may be different from each other.

As another example, as shown in FIG. 5B, the second display area DA2 mayhave a circular shape. In the case in which the second display area DA2has a circular shape, a single starting point may be provided. Thestarting point may include a third starting point S3 located at thecentral axis C. Position information of the third starting point S3 mayinclude an X-axis value circle_sx of the third starting point S3 and aY-axis value circle_sy of the third starting point S3.

The vertical length information of the second display area DA2 mayinclude the vertical length of the shape of the second display area DA2.The vertical length of the shape of the second display area DA2 maycorrespond to the difference between the smallest Y-axis value and thelargest Y-axis value, among coordinate values of a plurality of pointsconstituting the border of the second display area DA2. At this time,the y-axis value of the starting point may be the smallest Y-axis valueor the largest Y-axis value.

As an example, in the case in which the second display area DA2 has a Ushape, as shown in FIG. 5A, the vertical length information of thesecond display area DA2 may include the largest value notch_hei, amongvertical lengths between the plurality of points constituting the borderof the second display area DA2 and the first starting point S1.

As another example, in the case in which the second display area DA2 hasa circular shape, as shown in FIG. 5B, the vertical length informationof the second display area DA2 may include the largest value circle_hei,among vertical lengths between the plurality of points constituting theborder of the second display area DA2 and the third starting point S3.

The left border information, which is information about the left borderlocated at the left side based on the central axis C of the seconddisplay area DA2, includes direction information and width informationof each of a plurality of lines disposed within the vertical length fromthe starting point.

The left border information may include direction information and widthinformation of each of a first line, at which the starting point islocated, to an n-th line. At this time, n may correspond to the verticallength of the second display area DA2. For example, the vertical lengthof the second display area DA2 may be 20, in which case the left borderinformation may include direction information and width information ofeach of 20 lines from a first line, at which the starting point islocated, to a 20-th line.

The direction information included in the left border information mayindicate a direction in which the left border located at the left sidebased on the central axis C of the second display area DA2 moves fromthe first line to the n-th line.

Specifically, in the case in which the distance between the central axisC and a left border provided at a previous line is equal to or less thanthe distance between the central axis C and a left border provided at arelevant line, the direction information included in the left borderinformation may have a first direction value. That is, in the case inwhich the left border is parallel to or becomes distant from the centralaxis C, the direction information included in the left borderinformation may have a first direction value.

For example, in the case in which the left border is parallel to thecentral axis C, as shown in FIG. 5A, the direction information includedin the left border information may have a first direction value of 0.Alternatively, in the case in which the left border becomes distant fromthe central axis C, as shown in FIG. 5B, the direction informationincluded in the left border information may have a first direction valueof 0.

In the case in which the distance between the central axis C and theleft border provided at the previous line is greater than the distancebetween the central axis C and the left border provided at the relevantline, the direction information included in the left border informationmay have a second direction value. That is, in the case in which theleft border becomes close to the central axis C, the directioninformation included in the left border information may have a seconddirection value.

For example, in the case in which the left border becomes close to thecentral axis C, as shown in FIGS. 5A and 5B, the direction informationincluded in the left border information may have a second directionvalue of 1.

The width information included in the left border information mayinclude the width of the left border at each of the first line to then-th line. At this time, the width may correspond to the number ofpixels or subpixels provided in a relevant line. The width of the leftborder at each of the first line to the n-th line may be sequentiallystored as the width information included in the left border information.

The right border information, which is information about the rightborder located at the right side based on the central axis C of thesecond display area DA2, includes direction information and widthinformation of each of a plurality of lines disposed within the verticallength from the starting point.

The right border information may include direction information and widthinformation of each of a first line, at which the starting point islocated, to an n-th line. At this time, n may correspond to the verticallength of the second display area DA2.

The direction information included in the right border information mayindicate a direction in which the right border located at the right sidebased on the central axis C of the second display area DA2 moves fromthe first line to the n-th line.

Specifically, in the case in which the distance between the central axisC and a right border provided at a previous line is equal to or lessthan the distance between the central axis C and a right border providedat a relevant line, the direction information included in the rightborder information may have a first direction value. That is, in thecase in which the right border is parallel to or becomes distant fromthe central axis C, the direction information included in the rightborder information may have a first direction value.

For example, in the case in which the right border is parallel to thecentral axis C, as shown in FIG. 5A, the direction information includedin the right border information may have a first direction value of 0.Alternatively, in the case in which the right border becomes distantfrom the central axis C, as shown in FIG. 5B, the direction informationincluded in the right border information may have a first directionvalue of 0.

In the case in which the distance between the central axis C and theright border provided at the previous line is greater than the distancebetween the central axis C and the right border provided at the relevantline, the direction information included in the right border informationmay have a second direction value. That is, in the case in which theright border becomes close to the central axis C, the directioninformation included in the right border information may have a seconddirection value.

For example, in the case in which the right border becomes close to thecentral axis C, as shown in FIGS. 5A and 5B, the direction informationincluded in the right border information may have a second directionvalue of 1.

The width information included in the right border information mayinclude the width of the right border at each of the first line to then-th line. At this time, the width may correspond to the number ofpixels or subpixels provided in a relevant line. The width of the rightborder at each of the first line to the n-th line may be sequentiallystored as the width information included in the right borderinformation.

FIGS. 5A and 5B illustrate that the first direction value is 0 and thesecond direction value is 1. However, the present disclosure is notlimited thereto. In another embodiment, the first direction value may be1 and the second direction value may be 0.

The left border information and the right border information, describedabove, may be stored in the memory 160 while having a structure shown inFIG. 6 . For example, the left border information and the right borderinformation of each of six lines may be stored in 8 bytes.

Direction information of each of three successive lines may be stored in1 byte. For example, in 1 byte, among 8 bytes, direction informationline1 ld of the left border at a first line, direction information line1rd of the right border at the first line, direction information line2 ldof the left border at a second line, direction information line2 rd ofthe right border at the second line, direction information line3 ld ofthe left border at a third line, and direction information line3 rd ofthe right border at the third line may be sequentially stored in 1 biteach.

Width information of each of three successive lines may be stored in 3bytes. For example, in 3 bytes, among 8 bytes, width information of theleft border at the first line, width information of the right border atthe first line, width information of the left border at the second line,width information of the right border at the second line, widthinformation of the left border at the third line, and width informationof the right border at the third line may be sequentially stored in 4bits each.

Direction information of each of three lines following the previouslystored lines may be stored in 1 byte. For example, in 1 byte, among 8bytes, direction information line4 ld of the left border at a fourthline, direction information line4 rd of the right border at the fourthline, direction information line5 ld of the left border at a fifth line,direction information line5 rd of the right border at the fifth line,direction information line6 ld of the left border at a sixth line, anddirection information line6 rd of the right border at the sixth line maybe stored in 1 bit each.

Width information of each of three lines following the previously storedlines may be stored in 3 bytes. For example, in 3 bytes, among 8 bytes,width information of the left border at the fourth line, widthinformation of the right border at the fourth line, width information ofthe left border at the fifth line, width information of the right borderat the fifth line, width information of the left border at the sixthline, and width information of the right border at the sixth line may bestored in 4 bits each.

Hereinafter, concrete examples of the left border information and theright border information will be described with reference to FIGS. 7 and8 .

The second display area DA2 may have a U shape, as shown in FIG. 7 . Inthis case, starting points may include a first starting point S1 locatedat the left side of the central axis C and a second starting point S2located at the right side of the central axis C.

Shape information of the second display area DA2 shown in FIG. 7 mayinclude direction information and width information of each of a firstline, at which the starting points S1 and S2 are located, to an n-thline.

Since the left border at the first line line1, at which the startingpoints S1 and S2 are located, becomes close to the central axis C, thedirection information of the left border at the first line line1 mayhave a second direction value of, for example, 1. In addition, since theright border at the first line line1 becomes close to the central axisC, the direction information of the right border at the first line line1may have a second direction value of, for example, 1.

The width information of the left border at the first line line1 mayindicate the horizontal distance between the leftmost border pixel ofthe first line line1 and the leftmost border pixel of a second lineline2, which is located next thereto. Since the horizontal distancebetween the leftmost border pixel of the first line line1 and theleftmost border pixel of the second line line2 corresponds to sixpixels, the width information of the left border at the first line line1may be 6.

The width information of the right border at the first line line1 mayindicate the horizontal distance between the rightmost border pixel ofthe first line line1 and the rightmost border pixel of the second lineline2, which is located next thereto. Since the horizontal distancebetween the rightmost border pixel of the first line line1 and therightmost border pixel of the second line line2 corresponds to fivepixels, the width information of the right border at the first lineline1 may be 5.

It can be seen based on the width information and the directioninformation of the first line line1 that the leftmost border pixel ofthe second line line2 is disposed at the position of the second lineline2 moved from the leftmost border pixel of the first line line1 tothe central axis C by six pixels. In addition, it can be seen that therightmost border pixel of the second line line2 is disposed at theposition of the second line line2 moved from the rightmost border pixelof the first line line1 to the central axis C by five pixels.

Since the left border at the second line line2 becomes close to thecentral axis C, the direction information of the left border at thesecond line line2 may have a second direction value of, for example, 1.In addition, since the right border at the second line line2 becomesclose to the central axis C, the direction information of the rightborder at the second line line2 may have a second direction value of,for example, 1.

The width information of the left border at the second line line2 mayindicate the horizontal distance between the leftmost border pixel ofthe second line line2 and the leftmost border pixel of a third lineline3, which is located next thereto. Since the horizontal distancebetween the leftmost border pixel of the second line line2 and theleftmost border pixel of the third line line3 corresponds to fourpixels, the width information of the left border at the second lineline2 may be 4.

The width information of the right border at the second line line2 mayindicate the horizontal distance between the rightmost border pixel ofthe second line line2 and the rightmost border pixel of the third lineline3, which is located next thereto. Since the horizontal distancebetween the rightmost border pixel of the second line line2 and therightmost border pixel of the third line line3 corresponds to threepixels, the width information of the right border at the second lineline2 may be 3.

It can be seen based on the width information and the directioninformation of the second line line2 that the leftmost border pixel ofthe third line line3 is disposed at the position of the third line line3moved from the leftmost border pixel of the second line line2 to thecentral axis C by four pixels. In addition, it can be seen that therightmost border pixel of the third line line3 is disposed at theposition of the third line line3 moved from the rightmost border pixelof the second line line2 to the central axis C by three pixels.

The direction information and the width information of each of the thirdline line3 to a sixth line line6 may be set in the same manner as thedirection information and the width information described above. In anembodiment, in the case in which the distance between a border at arelevant line and the central axis C is equal to the distance between aborder at a next line and the central axis C, the width information maybe set to 0. For example, as shown in FIG. 7 , the distance between theleftmost border pixel of the sixth line line6 and the central axis C maybe equal to the distance between the leftmost border pixel of theseventh line line7 and the central axis C. In this case, the widthinformation of the left border at the sixth line line6 may be set to 0,since the horizontal distance between the leftmost border pixel of theseventh line line7 and the leftmost border pixel of the sixth line line6is 0.

The display device 100 according to the embodiment of the presentdisclosure may sequentially store the direction information and thewidth information of each of the first line to the n-th line in thememory 160 in the order of line. The display device 100 according to theembodiment of the present disclosure is capable of easily acquiring theborder of the second display area based only on the position informationof the starting point and the vertical length information, theline-based direction information, and the width information of thesecond display area, since the direction information and the widthinformation of each of the first line to the n-th line are sequentiallystored in the order of line.

Consequently, the display device 100 according to the embodiment of thepresent disclosure is capable of minimizing the amount of informationstored in the memory 160, whereby a small-capacity memory 160 may beused. In addition, the display device 100 according to the embodiment ofthe present disclosure is capable of acquiring the border of the seconddisplay area DA2 through simple calculation, whereby computational loadis low in processing for individually controlling the first display areaDA1 and the second display area DA2.

Also, in the display device 100 according to the embodiment of thepresent disclosure, it is sufficient to change only the shapeinformation of the second display area DA2 stored in the memory 160,whereby it is possible to easily change the shape of the second displayarea DA2.

Meanwhile, the memory 160 may further store edge information of edgeareas EA1, EA2, EA3, and EA4 in the second display area DA2. The edgeareas EA1, EA2, EA3, and EA4 may include a first edge area EA1 includingsecond subpixels SP2 provided in a first column of the second displayarea DA2, which is the disposed at the leftmost side thereof, a secondedge area EA2 including second subpixels SP2 provided in a second columnof the second display area DA2, which is disposed adjacent to the firstcolumn, a third edge area EA3 including second subpixels SP2 provided ina third column of the second display area DA2, which is the disposed atthe rightmost side thereof, and a fourth edge area EA4 including secondsubpixels SP2 provided in a fourth column of the second display areaDA2, which is disposed adjacent to the third column.

Edge information may include information about the second subpixels SP2provided in each of the first to fourth edge areas EA1, EA2, EA3, andEA4. The edge information may include information indicating whethereach of the second subpixels SP2 provided in each of the edge areas EA1,EA2, EA3, and EA4 is a light-emitting subpixel or a non-light-emittingsubpixel. In the case in which each of the second subpixels SP2 is alight-emitting subpixel, the edge information may have a first value of,for example, 1. In the case in which each of the second subpixels SP2 isa non-light-emitting subpixel, the edge information may have a secondvalue of, for example, 0.

The edge information may include an arrangement in which the secondsubpixels SP2 provided in each of the edge areas EA1, EA2, EA3, and EA4are sequentially stored according to the information thereabout. Forexample, in the case in which the first edge area EA1 is configured asshown in FIG. 9 , the edge information of the first edge area EA1 mayinclude an arrangement of “110011001100”. Meanwhile, in the case inwhich the third edge area EA3 is configured as shown in FIG. 9 , theedge information of the third edge area EA3 may include an arrangementof “001100110011”.

The display device 100 according to the embodiment of the presentdisclosure is capable of individually control the second subpixels SP2provided in the edge areas EA1, EA2, EA3, and EA4, since the edgeinformation is stored in the memory 160. Since the edge areas EA1, EA2,EA3, and EA4 of the second display area DA2 are disposed adjacent to thefirst display area DA1, the edge areas EA1, EA2, EA3, and EA4 of thesecond display area DA2 may be more easily recognized than the middleareas of the second display area DA2 due to a difference intransmittance or resolution. In order to prevent the edge areas EA1,EA2, EA3, and EA4 of the second display area DA2 from being recognizedby a user, it may be necessary for the second subpixels SP2 provided inthe edge areas EA1, EA2, EA3, and EA4 of the second display area DA2 tobe controlled in a different manner from the second subpixels SP2provided in the middle areas or to have a different structure than thesecond subpixels SP2 provided in the middle areas.

For example, the area decision unit 352 may decide image data ofsecond pixels P2, the display area information of each of which has asecond display area value or a third display area value, as image dataof the second display area DA2.

Meanwhile, the area decision unit 352 may decide image data of firstpixels P1, the display area information of each of which has a valuecorresponding to the first display area DA1, as image data of the firstdisplay area DA1. For example, the area decision unit 352 may decideimage data of first pixels P1, the display area information of each ofwhich has a first display area value, as image data of the first displayarea DA1.

The image correction unit 353 corrects the received image data byblurring the image data of the second display area DA2.

The weights W0, W1, W2, W3, W4, W5,W6, W7, and W8 of the plurality of areas may be different from eachother, or some may be equal to each other while some may be differentfrom each other.

The image correction unit 353 may dispose each of the plurality ofsecond pixels P2 provided in the second display area DA2 at the centerof the blurring filter, and may correct image data of the second pixelP2 disposed at the center of the blurring filter. Specifically, in thecase in which a specific pixel is disposed at the center of the blurringfilter, the image correction unit 353 may also dispose eight peripheralpixels surrounding the specific pixel in the blurring filter. The imagecorrection unit 353 may apply the weights W0, W1, W2, W3, W5, W6, W7,and W8 to image data corresponding to the specific pixel and the eightperipheral pixels, and may sum the image data having the weights appliedthereto. The image correction unit 353 may correct the summed image dataas image data of the specific pixel.

Meanwhile, the image correction unit 353 does not blur image data of thefirst display area DA1.

As a result, the image correction unit 353 may blur only image data ofthe second display area DA2.
